SPECIFICATION forming part of Letters Patent No. 661,315, dated November 6, 1900.

Application filed March 23, 1900. serial NO- (N0 DIOdGIJ T0 aZZ whozut it imty concern:

Be it known that I, ULGIs HOU-ZE, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Improvement in Leers, of which the following is a specification.

One aim and purpose of this invention is to construct a leer to be used in making window-glass wherein theleer can be easily 0perated and not get out of order.

A further object is to provide a leer with a carrying and a lifting frame, each separate and operated separately.

A further object is to provide each frame with bars for supporting the glass, the bars of each frame being connected together and moved simultaneously.

A still further object is to mount the carrying-frame so that it can be easily moved and not bind.

These and other objects not hereinbefore mentioned are accomplished by the construction illustrated in the accompanying drawings, wherein like letters of reference indi cate corresponding parts in the several views, and in which Figure 1 is a side elevation of a leer with the side wall removed, showing the sleeves in section. Fig. 2 is a top plan view of a leer with the cover removed. Fig. 3is avertical crosssection on the line 3 3, Fig. 1. Fig. 4is a tie tail perspective view of the sliding mechanism for supporting the carrying-frame. Fig. 5 is a detail perspective view of a portion of the carrying-frame, showing one side rail, cross-bar, and carrying-bar in position; and Fig. 6 is a detail sectional view of one of the carrying or lifting bars covered with a heatnon-conducting material.

In the drawings, Adesignates the side walls of the leer, and B the cover, both of the ordinary construction.

0 designates a series of boxes arranged at suitable intervals on opposite sides of the leer. These boxes are provided with a flange O, projecting from their lower inner edge, which extend into the brickwork in the side wall to support the boxes in place.

D designates wheels, one in each box. These wheels are supported on the edges of the box by means of their axles D, which are of suflicient length to rest on said edges. By this construction it will readily be seen that the wheels can roll in the box and he supported by the edges thereof. The move ment of the Wheels is limited by the shoulders D, near the opposite ends of the box. The wheels are provided with a flange D on the inner edge of their periphery. These wheels are adapted to support the carryingframe.

Resting on the series of wheels on each side of the leer is a bar E, forming the side rails of the carrying-frame. As plainly shown in Figs. 3 and 5, this bar is in the form of an inverted rail and for the sake of clearness will hereinafter be designated as such. At suitable intervals on the top of these rails are bolted clamps E, and in these clamps are secured the cross-bars F. As shown in Fig. 5, these cross-bars are composed of two channel-bars, which are spaced apart by means of the uprights H. These uprights are provided with a shoulder H, which rests on top of the crossbars. The lower ends of these uprights extend down between the two pieces of the cross bar and have their extreme lower ends bifurcated. They are secured to the cross-bars by means of the pins II, which pass through the bars and the bifurcations. The upper ends of these uprights are provided with a seat I, in which is positioned the carryingbar I. These bars consist of a horizontal base and an upright portion and the seat is made to correspond to this shape, so that the bars can be slid therein and securely held in place. These bars extend the whole length of the leer. As shown in Fig. 2, the rear ends of the rails E are connected by crossrods I, which form handles for moving the same and the carrying-bars. It will be no ticed that the carrying-bars form one set of the two sets of bars used in the leer. It will also be noticed that these bars are mounted on a rigid carrying frame, which in turn is supported by' the wheels D. By mounting this frame on the wheels the frame can be reciprocated with but little friction, there by preventing the frame from binding and dispensing with the necessity of oiling the bearings, which would be inexpedient owing to the intense heat in the leer during the process of annealing. The reciprocating movement of the sliding frame is limited by the shoulders D' and is held on the wheels bytheflangesDthereon. The lifting-frame consists of lifting-bars K and the other parts hereinafter immediately described forming the other set of bars in the leer. These bars are of the same form as the carrying-bars I and are supported by the same kind of uprights K as the uprights for the carrying-bars and are secured to cross bars K in a similar manner by means of bolts K as the other set of uprights. I

It will be noticed that by forming the carrying and lifting bars with a horizontal base and a vertical portion and a complementary seat on the upright the bars can he slid into the seats and securely held in place without the use of bolts. This construction is important for the reason that the bars are apt to warp and bend owing to the intense heat of the glass. In this construction the bars can either expand or contract,and not beingbolted to the seats can slide therein, and thereby prevent this warping and bending. They can also readily be removed.

The lifting-frame is raised and lowered as follows: Secured to the opposite ends of the cross-bars K is a chain L. These chains L extend upwardly through the side walls of the leer and are surrounded by the iron sleeves L. Bolted to the upper ends of these sleeves is a standard M, which have their upper ends bifurcated, forming bearing for the pulleywheels N N on the opposite sides of the leer, respectively. On the inner sides of these wheels is a smaller wheel 0, to which the upper ends of the chains L are secured. It will be seen from this construction that if the wheels N N are rotated that the cross-bars K and the lifting-frame will be raised and lowered by means of the lifting-chains L, connecting the ends of the bars with the small wheels 0 on the side of the wheels N N, respectively.

At the rear end of the leer, as shown in Fig. 2, is positioned ashaft P,whicl1 extends across the rear end of the leer and is mounted in the standards P. On the opposite ends of this shaft are rigidly secured pulley-wheels R R, respectively. Secured to each pulley-wheel R R, respectively, is a chain S S, respectively,which ext nd upwardly around the pulley-wheels N N, respectively, and have their other ends secured to the last wheel on-the front end of the leer. The shaft Pis rotated by means of the hand-lever T. From this construction it will be seen that the lifting-bars are raised or lowered by simply moving the lever to the right or left. In Fig. 1 the lifting-frame is up, and by moving the lever to the right, as shown in dotted lines, the frame will be lowered below the carrying-frame. By having a flexible connection between the wheels it obviates all danger of the wheels being disconnected owing to expansion and contraction formed by the heat if a rigid rod were used. I.

In Fig. 6 I show a modification wherein the carrying and lifting bars are covered with asbestos U or other non-conducting heat material. In this construction I preferably use a pieceof asbestos pressed into shape so as to snugly fit over the rails and leave a small space U between the upper edge of the rail and asbestos and bring the asbestos down, forming shoulders U", which rest on the flat portion of the rail, and also provide the flanges U, which grasp the sides of this flat portion. By this construction the asbestos is not only firmly held on the carrying-bar, but the Weight of the glass will be carried by the fiat portions of the bars, so that the upright portions of the bars cannot split the asbestos. These pieces-of asbestos must be divided into longitudinal sections, so as not to interfere with the seats I on the uprights.

The operation of my device is as follows: In Fig. 1, after the lifting-frame carrying the lifting-bars has been lowered below the carrying-frame supporting the carrying-bars the carrying-bars will be in position to receive a sheet of glass from the flattening oven. (Not shown.) After the sheet is on the carrying-bars the carrying-frame is moved to the left the whole space allowed between the shoulders D" on the box D. When this is done, the lifting-bars are raised, lifting the glass from the'carrying-bars, so that the carrying-frame can be moved to the right and the operation repeated. When the carryingframe is moved to the left, there will be a sheet of annealed glass to be taken therefrom at the left end of the machine in the usual manner.

I am aware that many minor changes can be made in the construction and arrangement of parts without in the least departing from the nature and principles of my invention.
